Hint: CNG is a gas which is used very commonly. It is most commonly used in automobiles as a fuel. It is also being promoted as a fuel because it does not harm the environment. The main component in it is the first member of the Alkanes family.

Complete step by step answer:
C.N.G. is a clear, transparent, odourless, non-corrosive gas which is being used as a cheaper, cleaner and a more efficient alternative to other fuels. C.N.G. is the short form of compressed natural gas. As the name suggests, C.N.G. is manufactured by compressing natural gas to less than one percent of the volume it occupies at standard atmospheric pressure (STP condition refers to the condition when pressure is equal to 1 atm and temperature is equal to 273.15K).
Natural Gas is mainly composed of Methane \[(C{{H}_{4}})\].
C.N.G. is stored in hard containers at a pressure of around 20-25 MPa, in cylindrical or spherical shapes.
C.N.G. offers many advantages, such as –
• It burns cleaner, i.e. it produces very less greenhouse gases when compared to the traditional fuels.
• Carbon emission produced by it is very less.
• Since C.N.G. is not toxic, it does not contaminate groundwater.
• Vehicles operating on CNG fuels produce a lot less noise when compared to gasoline and diesel vehicles, thus reducing noise-pollution.
• It is also very cost effective.
• It is also very less flammable and is not a big risk for fire hazards, when compared to other fuels.
Therefore, the answer is option (b) – methane.

Additional information:
We generally see cylindrical containers in many vehicles – it is a C.N.G. tank.

Note: C.N.G. is very popular for its use instead of used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG).Not only this, it is also used in households for cooking and heating purposes.
